In the experiment of anaerobic respiration of yeast what happened to the lime water or hydrogen carbonate indicator solution in it?
In the experiment of anaerobic respiration of yeast, the yeast ferments sugars and produces carbon dioxide as a byproduct. When carbon dioxide is bubbled through lime water (calcium hydroxide solution), it reacts to form calcium carbonate, which causes the lime water to turn cloudy. If a hydrogen carbonate indicator solution is used, the increase in carbon dioxide leads to a color change, typically becoming more acidic and resulting in a shift in color depending on the pH change. This indicates the production of carbon dioxide during yeast fermentation.
How can you determine gasses present in solution using the expermints with BTB?
Bromothymol blue (BTB) can change color in the presence of carbon dioxide or acidic solutions, turning from blue to yellow. By observing the color change in a solution with BTB added, you can determine the presence of carbon dioxide or acidity levels, which can help identify certain gases like carbon dioxide in the solution.
How do you text for carbon dioxide?
To test for carbon dioxide, you can bubble the gas through limewater (calcium hydroxide solution). If carbon dioxide is present, it will cause the limewater to turn milky or cloudy due to the formation of calcium carbonate. Another method is using a pH indicator like bromothymol blue, which will change color in the presence of carbon dioxide.
What color does bicarbonate indicator change to?
Bicarbonate indicator changes color from orange-yellow to red when exposed to carbon dioxide. This change is due to the formation of carbonic acid, which shifts the pH of the solution causing the indicator to change color.
Does hydrogen carbonate indicator shows any color with oxygen?
No, hydrogen carbonate indicator does not change color when exposed to oxygen. It is mainly used to detect the presence of carbon dioxide, as it turns pink in the presence of an acid (carbon dioxide dissolved in water forms carbonic acid).
What happens when carbon dioxide is bubbled into hydrogen carbonate indicator?
When carbon dioxide is bubbled into a hydrogen carbonate indicator, the indicator solution will turn yellow. This is due to the formation of carbonic acid, which is a weak acid. The carbon dioxide reacts with water in the indicator solution to form carbonic acid, causing the color change.
Bromothyl blue and water were bubbled explain why the solution colour changed?
The solution's color changed because bromothymol blue is a pH indicator that changes color based on the acidity or alkalinity of the solution it is in. When bubbled with water, carbon dioxide from the air dissolves in the water, forming carbonic acid, which lowers the pH of the solution, causing the bromothymol blue to change color.
Why does the color change on a leaf from top and bottem?
carbon dioxide
Give the test for carbon dioxide?
The most common colorimetric test for carbon dioxide gas involves using limewater (calcium hydroxide solution). When carbon dioxide is bubbled through limewater, it forms a white precipitate of calcium carbonate, indicating the presence of the gas. Additionally, using a pH indicator paper that changes color in the presence of carbon dioxide can also be a simple test.
Why does carbon dioxide change colors of indicator?
When carbon dioxide dissolves in water, it forms carbonic acid, which can change the pH of the solution. Indicators are substances that change color depending on the pH of the solution, so when the pH changes due to the presence of carbonic acid, the indicator may change color accordingly. This is how carbon dioxide can affect the color of an indicator.

What color is carbon dioxide?
Carbon dioxide is colorless.
Will the color of the color changes if carbon dioxide oxygen water and why?
The color of a substance may change when it reacts with carbon dioxide, oxygen, or water depending on the specific reactive properties of the substance. For example, some compounds may undergo oxidation or reduction reactions leading to a change in color in the presence of oxygen or water. However, carbon dioxide is unlikely to directly impact the color of a substance.
What color does phenol red change to when carbon dioxide is present?
It turns a yellow-ish color when CO2 is added.
What is the color of the carbon dioxide molecule?
Carbon dioxide gas is colorless
What is a chemical indicator for carbon dioxide?
Bromothymol blue is a chemical indicator that can be used to detect the presence of carbon dioxide. In the presence of carbon dioxide, the indicator changes color from blue to yellow. This change in color indicates the presence of carbon dioxide gas.
Carbon dioxide and bromothymol blue?
Carbon dioxide can react with water to form carbonic acid, which can lower the pH of a solution. Bromothymol blue is a pH indicator that changes color from blue to yellow in acidic solutions. When carbon dioxide is bubbled through water containing bromothymol blue, the solution will turn yellow due to the decrease in pH caused by the formation of carbonic acid.
